What is Active-Active Clustering


What is Active-active Clustering?

Active-active clustering is a data resiliency architecture in which client workloads are distributed across two or more nodes in a cluster to keep your data safe and available in the event of an unexpected component failure.

The Benefits of Active-active Clusters

Common benefits of active-active clusters include:
  • High availability of mission-critical apps across data centers, campuses, and metros
  • Load balancing across a cluster of servers
  • Data redundancy and resiliency (maintain uptime even when one site fails)
Why Active-active vs. Active-passive?

When it comes to high-availability (HA) clusters, the two main configurations you’ll encounter in data storage are:
  • Active-active clusters: Client machines connect to a load balancer that distributes their workloads across multiple active servers.
  • Active-passive clusters: Client machines connect to the main server, which handles the full workload, while a backup server remains on standby, only activating in the event of a failure.
